This is now a different error code.
It's an authorization error.

Did you set the owner authorization (aka storage hierarchy) ?
That needs to be passed using -P

Betreff: RE: [tpm2] Some Errors
That seems to not have been updated correctly.
 
Should probably be:
tpm2_evictcontrol -c ak.ctx 0x81010002
or
tpm2_evictcontrol -C o -c ak.ctx 0x81010002
 
Maybe you could try this and if it works, make a PR with the update to the tools project.
 
Thanks,
Andreas

Hi,
 
I tried to make my ak persistent, usign the following readme:
 
 
The first two commands work fine, the last one results into:
 
tpm2_evictcontrol -c 0x81010002 -o ak.ctx

I am not sure, whether I need to run any cmd to allocate the handle, or if it is necessary to be in a special mode or sth. Can you help me with this issue? Thanks a lot.
 
Best regards
